How much have you done to your world? My buddy and some friends previously built a fortress and one of them proceeded to build a HUGE moat around it. The game now lags horribly and is basically unplayable because of the level of customization done to their world.

So he now plays on mine, where the only rule is "No Moats"...

Not to say it isn't a bad idea, because the enemies that fall in, die or can be shot and killed from the wall, but the benefit does not out weigh the cost in this aspect haha!

Also, this was for random encounters, and for size reference, its large enough where trolls will fall in and can't harm anything. It also forms a full perimeter of their base, which isn't small to begin with. Its impressive actually. If it didn't break the game, I'd be in love with it!
